Who Wore The Most Revealing Outfit To The SI Swimsuit Issue Gala Celebration?

Can you believe Sports Illustrated’s revered tradition of ignoring athletes for one issue a year and devoting an issue to lovely ladies rolling around in sand has been going on for half a century now? Good ideas do have staying power! Last night, longtime veterans — Kathy Ireland, Cheryl Teigs, Heidi Klum — of the Swimsuit Edition partied with newbies (and wannabes, like Ireland Baldwin) in Hollywood, for a celebration that will eventually be televised on NBC on February 3.
Some of the models in attendance showed up in fancy dresses that tastefully covered the assets they so willingly show off in the magazine’s pages. The heavy, zippered dress on Heidi Klum — who’s hosting the show — has us wondering if she did a strip tease once the show started. Others, like Kate Upton, just can’t seem to contain the assets that make them famous, even in a floor-length gown. We’ve organized the gallery above from most- to least-clothed, for your viewing pleasure. This will have to tide you over until the 2014 edition’s release on February 11.
